Although Pleurotus abalonus is a well-known edible mushroom in Asia, there is a dearth of information on its antioxidant activity. The present report is the first one focused on the purification and characterization of 9-beta-d-ribofuranosidoadenine (ADO), 5¡ä-deoxy-5¡ä-(methylthio) adenosine (MTA) and a triterpenoid complex from P. abalonus. Different antioxidant activities including inhibitory effects on hemolysis and lipid peroxidation in brain and kidney homogenates as well as significant synergistic effect on scavenging of hydroxyl radicals were demonstrated, which lays a foundation for the development of P. abalonus as a natural antioxidant applied in medicine.
